STAPLE-SETTING TOOL.

Specification of Letters Patent.

Patented Oct. 10, 1911.

type wherein a pair of para el jaws are moved toward one another by the manipulati on of a pair of handles, and one of which jaws carries a strip of staples, and the o posite jaw being provided with a heat or plunger which severs the outer sta 1e of the strip and drives the same throng a numher of sheets of paper or like materiaL- The principal objects of our invention are first: to provide a sim 1e staple setting :toolwhich is operated wi the pressure of the hand similarto the operation of a p9. of pliers thereby eliminating the. poun ing movement usually employed in sta 1e setting machines to arrange on one of t e jaws a rejecting blade adapted to pierce a. sheet 0 paper or an envelop prefers 1y at a point adjacent the sealing flap, in order that a series of staples may be forced through the sealing flap and a portion of the envelo to provide means for holding the stap e strip in roper position upon one of the jaws and to eed said strip forward to bring the outer sta le of the strip into position to be engaged y the hammer or plu or carried by the opposite jaw, and to. rovide a feed-. ing dog or member which wi automatically disengage from the strip of staples and slip over the tops of the forward staples of the strip whenever the device is partially actuatcc and the forward end of the strip of staples is in position to be engaged by the severing and driving head or plu er.

lVith these objects in view our invention consists in certain novel features of construction and arran ement of parts hereinafter more fully escribed, claimed and shown in the accompanying drawings, in which-;

forming part of this Figure 1 is a side elevation of a staple setting tool of our improved construction. Fig. 2 is avertical section taken through the center of our improved staple setting tool. Fig. 3 is a horizontal section taken on -theline 3-3 of Fig. 1. Fig. 4 is a detail section taken on the ine 4- -4 of Fi 1. Fig. 5 is an enlarged sectional view i1 ustratin the lower end of the staple feeding dog, an a ortion' of the staple strip carry ng aw.

ferring by numerals to the accompanying drawings 1 and 2 designate the jaws of our improved tool, and formed on or fixed tothe lower jaw 1 and projecting forwardly therefrom is a blade 3, the'forward end of which is pointed, and the sides'of'which are rovided with knife edges in "order that said lade cam be. readily inserted through a sheet of=paper or the like. The blade 3 rejects from the under side of the forwa'r portion of the jaw 1 and formed between the central portion of the vblade andthe forward end of the jaw 1 isa slot 4 adapted to receive the paper or ma- ,terial through which the staples are driven. Formed in the to surface of the blade immediately below e forward endof the jaw 1 is a pair of de ressions 5 into which the lower ends of t e staple legs engage [when driven, and said depressions are so formed as to deflect the ends of the staple legs upwardly, thereby clenching the same on the under side of the paper.

A pair of handles 6, such as are ordinarily used u on pliers and like tools, have their forwar ortions bifurcatedinorderto enga the si es of the jawsl and 2, and the orward ends of-these bifurcated portions dre pivotally mounted upon pins 7 seated in the sides of the jaws 1 and 2. The bifurcated forward ends of the handles 6 are pivotally connected to one another by means'of pins or rivets 8 and seated in said handles 6 to the rear of the pivot pins or rivets 8 are transversely dis osed pins 9 nvhich pass through slots 10 ormed in the rear ends of the jaws 1 and 2. .The construction just described provides means whereby the jaws 1 and 2 are held arallel with one another, and maintain suc relative positions during movement, to and from one another.

The forward ends of retractile coil springs therefrom 15 an arch 11 are connected tothe rear ends of the jaws 1 and 2 and the opposite ends of said springs are connected to the outer portions of the handles 6. These springs normally hold the jaws 1 and 2 apart and oppose the movement of'the handles 6 toward one another.

F ormcd in the top surface of the jaw 1 adjacent the side edges thereof is a pair of parallel grooves 12 which receive the legs of the staples which latter, in strip form, lie immediately upon the lower jaw 1 between said grooves 12.

Formed integral with or fixed to the forward ortion of the jaw 1 and projecting inwar ly from the sides thereof are lips 13, which overlie the forward portion of the staple strip, thus preventing the forward portion of said strip from buckling or moving away from the to side of the aw 1. ixed to the centre ortion of te jaw 1 and extending upwar a short distance 14 carrying a longitudinally disposed fiat spring 15 the rear end of which normally bears upon the rear portion of the staple striP,. and the forward end of said spring being bent into inverted U-shape as desi ated by 16, and the points, formed by ben ing engage between-a pair of the staples ad'acent the forward end of the strip there y preventing the strip from. movin rearward uring the rearward movemento the staple feeding dog hereinafter described.

Depending from theforward end-of the jaw 2.is a head on plunger 17 which preferably occupies a position at rightangles to the jaws 1 and 2. The ,rearside of this plunger 17 is adapted to move across the forward end of the jaw 1, and during this movement the rear lower corner of said plunger 17 combines with the upper corner on the forward end of the aw 1, to shear or cut the forward one of t e sta les from the strip, and the continued ownward movement of the plunger forces the legs of the severed staplethrough the thickness of paper'or like material 1 ing on top of lade 3 and within the s ot 4.

Formed in the sides of-the plunger 17 are vertically disposed grooves 18 and formed on or fixed to the forward end of the jaw 1 and projecting upward from the sides thereof are fingers 19 which are adapted to ride in the grooves 18, when the jaws move toward and from one another. These fingers 19 are for the purpose of preventing the pa er or material into which the staples are being drivenfrom being inserted between the jaw 1 and the lower end of the plunger 17.

livotally mounted on the under side of the jaw 2 is the upper end of the feed dog 20 which as shown is in the form of a straight lever, the lower end of which is of the forward end of this spring,

the

inverted U-sha said lower on tgp of the jaw 1 adjacent the forward end 0 the 5 ring 15. The lower portions of the inverte U-shaped lower end of the feed dog are sli htly rounded off or beveled as designated hy 93 in order that the forward.

as designated by 21, and normally resting upon the end of the feed dog will slip over the bodies of the staples at the time the j aws are moved toward one-another, and the forward one of the staples is in position to be engaged, severed and driven by the plunger 17. The forward end of the feed dog '20 is normally foroed'downward by a spring 241- llxed to the underside of the jaw 2, and bearing on top of said feed dog.

The operation of our improved staple setting too is as follows: \Vhcn the handles 6 are manually engaged and moved toward one another in parallelism the plunger 17 moves in a straight line across the forward end of the jaw 1 and the forward one of the strip of. staples upon said jaw is engaged lay the plunger, is severed from the next a jacent sta lo, and said severed staple is forced ownward through the layers of paper occu ying the slot 4 between the aw 1 and blhde 3, and the legs of said severed staple are clenched on the under side of the paper.

After the pressure of the handles 6 is relieved the power stored in the coil springs 11' returns. the arts .to their normal positions as seen in *igs. 1 and 2.

The staple strip is moved forward upon the jaw 1 by the staple feeding dog 20, a

oint of which engages between a pair of sta ples of the strip, and which feeding movement is accomplished when the handles 6 are moved toward one another. During this feeding forward movement the curved or beveled lower ends 23 of the inverted U- shaped forward end of the staple feeding dog engage behind one of the staples, and as the 'aws 1 and 2 are moved toward om anot er the lower end of the feeding do; moves forward, thus feeding the staple stri forward upon the jaw 1. Immediately after this staple feeding movement takes place tlr lower end of the plunger 17'engages thforward one of the staples and which for ward staple projects beyond the end of th jaw 1. he feeding forward movement 0 the staple stri is stopped by the enga t ment of the forward one of the sta ie against the fingers 19, and during su s1 quent partial actuation of the handles and, jaws 1 and 2 the lower end of the stapY feeding dog will slip over the .strip l staples by reason of the inclined or bcvolc lower ends 23.

In Fig. 2 we have shown the blade inset ed through the body portion of an envel adjacent the portion engaged by the sealii flap, and thus it will be seen that a numb allel jaws, means ward and from one another in parallelism, a

upon said jaw, and means carried of staples can be inserted through the sealing flap and the body of an envelop, even after the envelop is sealed, and which action leaves only a small slit through the body of the envelop.

A staple setting tool of our improved construction is comparatively simple, is very compact, provides means for setting nlcs through the sealing flap of an enver or through the doubled over ends of the wrappers of packages and bundles, and said tool is operated with a gripping movement of the hand in place of a pounding movement required by a number of staple setting devices now in general use.
